A M3.4 quake in the San Bernardino Mtns. was felt just after midnight last night. The time was 12:03 am, and the epicenter was located 5 miles east-northeast of Big Bear City. Since aftershocks of the 1992 Mw6.2 Big Bear quake (itself an aftershock of the Mw7.3 Landers quake) have been almost nonexistant in the past couple of years, it is probably unfair to label last night's quake an aftershock.
